With newly appointed chairman Yoshikazu Maruyama, SeaWorld hopes to boost its appeal in the family entertainment industry.

Maruyama has over 20 years of experience in theme parks and family entertainment. He helped lead the early turnaround of Universal Studios Japan, which was recently acquired by Comcast NBCUniversal.

The company has also elected Donald C Robinson as lead independent director, effective October 9.

"I am honoured to succeed David and want to express my deepest appreciation to him for his years of dedication to SeaWorld," Maruyama said. "I am excited to bring a fresh perspective to the board and am deeply committed to working with the management team to deliver memorable guest experiences, extend SeaWorld's iconic brands to global audiences, improve business performance, and enhance value for shareholders and all our important stakeholders."

Robinson said: "Our board is committed to continuing to advance its governance standards and independence and we believe that, by establishing these two complementary roles with clear responsibilities, we can enhance the rigorous and independent oversight of the company and the board. Yoshi and I intend to work closely with the other directors and the management team to advance the company's progress on behalf of all its shareholders and other stakeholders."
